SRS Warning Light System Malfunction (Always lit up when igni-
tion switch is in LOCK position.)
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.
When the SRS is normal, the SRS warning light lights up for approx. 6 seconds after the ignition switch is
turned from the LOCK position to ACC or ON position, and then turns off automatically.
If there is a malfunction in the SRS, the SRS warning light lights up to inform the driver of the abnormality.
When terminals Tc and E1 of the DLC1 are connected, the DTC is displayed by the blinking of the SRS warn-
ing light.

INSPECTION PROCEDURE
1 Preparation.
PREPARATION:
(a) Disconnect negative (-) terminal cable from the battery,
and wait at least 90 seconds.
(b) Remove steering wheel pad (See page SR-13).
(c) Disconnect connector of front passenger airbag assem-
bly (See page RS-21).
CAUTION:
Store the steering wheel pad with the front surface facing
upward.
2 Does SRS warning light turn off?
PREPARATION:
(a) Disconnect airbag sensor assembly connector.
(b) Connect negative (-) terminal cable to battery.
CHECK:
Check operation of SRS warning light.
NO Check SRS warning light circuit or terminal AB
circuit of DLC1.
YES
Replace airbag sensor assembly.

3 Check SRS warning light circuit.
PREPARATION:
(a) Connect negative (-) terminal cable to battery.
(b) Turn ignition switch to ACC or ON.
CHECK:
Measure voltage LA terminal of harness side connector of air-
bag sensor assembly.
OK:
Voltage: 10 - 14 V
NG Check SRS warning light bulb / repair SRS
warning light circuit.
OK
4 Does SRS warning light come on?
PREPARATION:
(a) Disconnect negative (-) terminal cable from the battery.
(b) Connect airbag sensor assembly connector.
(c) Connect negative (-) terminal cable to battery, and wait
at least 2 seconds.
(d) Turn ignition switch to ACC or ON.
CHECK:
Check operation of SRS warning light.
NO Check terminal LA of airbag sensor assembly.
If normal, replace airbag sensor assembly.
YES
From the results of the above inspection, the malfunctioning part can now be considered normal.
To make sure of this, use the simulation method to check.

4 Check airbag sensor assembly.
PREPARATION:
(a) Turn ignition switch to LOCK.
(b) Disconnect negative (-) terminal cable from the battery,
and wait at least 90 seconds.
(c) Remove steering wheel pad (See page SR-13).
(d) Disconnect connector of front passenger airbag assem-
bly (See page RS-21).
(e) Disconnect connector of airbag sensor assembly
(See page RS-33)
(f) Insert service wire into terminal Tc from back side as
shown.
(g) Connect airbag sensor assembly connector with service
wire.
(h) Connect negative (-) terminal cable to battery.
(i) Turn ignition switch to ACC or ON and wait at least 20 se-
conds.
(j) Connect service wire of terminal Tc to body ground.
CHECK:
Check operation of SRS warning light.
OK:
SRS waning light comes on.
NOTICE:
Never make a mistake with the terminal connection posi-
tion as this will cause a malfunction.
OK Check harness between airbag sensor assem-
bly and DLC1.
NG
Replace airbag sensor assembly.

If the DTC is displayed without a DTC check procedure, do the following trou-
bleshooting.
1 Check resistance between terminal Tc of airbag sensor assembly and body
ground.
PREPARATION:
(a) Turn ignition switch to LOCK.
(b) Disconnect negative (-) terminal cable from the battery,
and wait at least 90 seconds.
(c) Disconnect airbag sensor assembly connector.
